Knott's really once was a berry farm. Walter Knott built a themed Ghost Town to entertain diners waiting for tables at his wife's fried chicken restaurant. Over the years, the park grew into a destination of its own. Today, the park is owned by the Cedar Fair company. Knott's Berry Farm is located in Buena Park, California, about 45 minutes south of Los Angeles and five minutes west of Disneyland.
Note on food: The star food attraction, Mrs. Knott's Chicken Dinner Restaurant, is actually located outside the park. That means you do not need park admission to dine there, but it does mean you'll have to get your hand stamped and exit if you are visiting the theme park.
